Siemens 1FK7034-2AF21-1QA0 SIMOTICS S 1FK7-CT 1.6 Nm 3000 rpm Servo Motor

Siemens 1FK7034-2AF21-1QA0 SIMOTICS S 1FK7-CT servo motor delivers 1.6 Nm standstill torque and 0.47 kW rated power at 3000 rpm on a 300 V DC link. It is a 6-pole design with 1.8 A rated current, IP64 protection, a 20-bit single-turn absolute encoder (AS20DQI) with a DRIVE-CLiQ interface, and no holding brake.

Selection Notes

This is the non-brake version of the 300 V, 3000 rpm 1FK7034-CT variant: without the brake, rotor inertia is 0.900 kgcm² and shaft torsional stiffness is 5,300 Nm/rad, both better than the holding-brake version in the same frame. It steps up from the 1FK7032 frame with more torque (1.6 Nm) and a higher 1.8 A rated current at the same 300 V DC link and 3000 rpm rated speed. Use it where an external holding mechanism already exists and inertia matching favors the lighter, non-brake rotor.

Applications

1.6 Nm at 3000 rpm without a brake suits horizontal indexing axes, small conveyor drives, and pick-and-place heads in machine-tool and packaging cells where holding torque at standstill is not required.
